A detection system device for heat meter comprises a first circulatory pipeline, a second circulatory pipeline and a system measuring and controlling device. The first circulatory pipeline at least comprises a conduit. A first measuring pipe is in series arranged in the conduit, and is provided with a temperature sensor with a standard inlet. The exit of the first measuring pipe is connected with a calibrated instrument. The first circulatory pipeline is further provided with a first flow sensor. The second circulatory pipeline comprises a conduit and a second measuring pipe in series arranged in the conduit. The second measuring pipe is provided with a temperature sensor with a standard exit. The second circulatory pipeline is further provided with a second flow sensor. The system device provided by the utility model is capable of detecting the reading accuracy of a heat meter, and of detecting other service performances of the calibrated instrument.
